No built-in WhatsApp channel
The bridge had to be built.
BoldBellowsVoiceflow WhatsApp agents for businesses whose customers are on WhatsApp
The documented channels are the widget, phone, SMS and the API, so WhatsApp runs through the conversation API with a relay that carries Meta's messages, using the customer's number as the user ID. BoldBellows records the customer's number, the message and the template or window it sits in before a reply is drafted, relays each WhatsApp message to the agent through the conversation API and replies in the right window, then builds the relay that verifies each webhook from the WhatsApp Cloud API, sends the customer's text to the agent with a PUT request keyed on their number, turns the traces that come back into WhatsApp messages, buttons and lists, checks the 24-hour window before every reply and switches to an approved template when it has closed, and passes the customer to a person together with the conversation.
One-off setup from $1,470
No monthly subscription
Chapter 01 the not-a-built-in-channel problem
Voiceflow's documented ways to reach customers are the web widget, phone, SMS and its API. WhatsApp is not on the list, so a WhatsApp agent means a bridge: something must receive Meta's webhooks, pass each message to the agent, and carry the replies back. A weak bridge treats a repeated webhook as a new message, ignores the 24-hour window and fails when the agent returns a card or a carousel that WhatsApp cannot show. The business sees an agent that answers twice, goes silent overnight and cannot start a conversation because the template was never approved.
WhatsApp stopped being the one channel the agent could not reach.
The bridge had to be built.
Duplicates were not recognized.
No template was ready.

Chapter 02 How it works
On this Voiceflow WhatsApp AI Agent service, a change is tested against the rule, matched to its proposal by key, and written only if it adds something.
The source and time of the event are recorded and the Voiceflow event is judged against your admission rule before anything happens.
The webhook is verified, the text is relayed to the agent, and the traces are translated.
The window is checked, the reply or template is sent, and hard cases go to a person.
Chapter 03 What ships in the build
With Voiceflow WhatsApp AI Agent in place, three jobs share the work: Core decides, Extended acts and Audited verifies.
Screens the Voiceflow events that arrive from Voiceflow so only those you agreed to can start work.
Keeps a decision record for each Voiceflow signal: the inputs, the evidence, the confidence and the approval state.
Strips every Voiceflow value that has no job in the AI workflow before the write is made.
Receives WhatsApp webhooks and calls the conversation API.
Reads one key built from the customer's number, the conversation, the knowledge version and the model run on each arrival and files the record as new, updated, done or unclear.
Decides how each trace is shown and whether a template is needed.
Finds drift between Voiceflow and the AI workflow early and keeps a dated list for an owner to clear.
Flags chats near the end of the 24-hour window.
Ranks unresolved the AI workflow items by age and shows who has to act on each, for this Voiceflow WhatsApp AI Agent service.

Chapter 04 Who this fits
Customers want to talk to your agent on WhatsApp, and since it is not a built-in channel, the bridge has to be reliable.
"Answer me on WhatsApp."
I get a reply in seconds.
"Keep the agent's quality."
The same agent answers everywhere.
"Build a reliable bridge."
Webhooks are verified and deduplicated.
"Stay inside the rules."
Windows and templates are handled.
"One agent to maintain."
WhatsApp is just another channel.
"Show what was said."
Transcripts keep the thread.
Chapter 05 The options
Each can run an auto-reply. Only one relays Meta's messages to the agent through the API, keeps the window in view and uses templates after it.
| Question | An auto-reply | A generic bridge | Our API-relayed WhatsApp agent |
|---|---|---|---|
| What starts the work | A person checks the screen | Each Voiceflow event the connector was pointed at | Only Voiceflow events the rule approves |
| How identity is decided | A person types the name into a search box | Matching depends on spelling | Customer number, message, conversation and window state |
| What reaches the AI workflow | Values copied by hand | A single block of plain values | An agent reply translated for WhatsApp, or an approved template, with a handoff when needed |
| After an uncertain result | Two tabs and a spreadsheet | Nothing tells anyone it failed | Compares live state first, then repairs or routes to an owner |
The route ranks events by their own timestamps and keeps the newest state, so a delayed Voiceflow notice does not roll back a proposal.
The message ID is recognized, the agent is not invoked a second time, and the customer receives one reply. One key built from the customer's number, the conversation, the knowledge version and the model run drives a lookup whose result is one of absent, matching, changed or in doubt.
Nothing is mapped until one key built from the customer's number, the conversation, the knowledge version and the model run is chosen, since each later rule refers back to it.

Chapter 06 The process
For Voiceflow WhatsApp AI Agent, six stages, one output each, take you from the first request to a month of live running.
About 30 minutes
We review your WhatsApp Business account, your templates, your agent and where the bridge will run.
Access review
Limited access to Voiceflow is arranged, the model provider is chosen with you, and the fields that identify each decision are agreed.
Most of the project
How traces map to WhatsApp messages, what happens at the window's edge and who takes handoffs are written out and approved first.
Before you review
Duplicates, late events and permission changes are run through a rehearsal copy of the AI workflow first, in the Voiceflow WhatsApp AI Agent service.
Handover day
With Voiceflow WhatsApp AI Agent in place, nothing goes live until you have read the launch notes and said yes, and the first live runs are watched closely.
About 30 minutes
With Voiceflow WhatsApp AI Agent in place, at the end of month one we go through volume, exceptions and retries together and tune the route.
Chapter 07 Turnaround
Delivery time runs from approved access to Voiceflow and the model service.
6 to 10 business days
10 to 16 business days
16 to 24 business days
Chapter 08 Getting started
Chapter 09 Trust
Approved Voiceflow data goes to the model, a typed proposal comes back, and your policy decides whether anything is written.
Everything the route does with Voiceflow and the AI workflow goes through the access each vendor publishes, and nothing hidden is relied on.
In the Voiceflow WhatsApp AI Agent service, every key is scoped to a single job, and you can retire any of them at once without touching the rest.
Each value that reaches the AI workflow is on a written list with the reason beside it, and the rest of the Voiceflow record is left alone.
Because one key built from the customer's number, the conversation, the knowledge version and the model run travels with the proposal, a second attempt can be told apart from a first one that simply arrived late.
The log records that something happened and how it ended, not what the Voiceflow record said.
Along with the build you get the diagram, the credential register and the repair guide, all of them yours to keep, on the Voiceflow WhatsApp AI Agent service.
"When a channel is not built in, the honest work is the bridge, and the bridge has to be right."

Clients love the transparency and we love the time we get back. Productivity is up, and project delays have dropped to almost zero.

AI Chatbot & Customer Support
BoldBellows built an AI support chatbot for our online boutique, and it has changed how we run the business. We used to have two full-time staff answering the same questions all day. Now the AI handles order tracking, product recommendations and even refund requests on its own.
What surprised me most is how natural it sounds. Customers compliment the ‘agent’ without realizing it’s AI. Our support workload dropped by 75% and customer satisfaction went up dramatically.
AI Content & Social Media Automation
Our marketing agency couldn’t keep up with content. BoldBellows set up an AI content engine that writes blog posts and captions and even designs our social media creatives.

BoldBellows automated our product listings. The AI writes descriptions, organizes photos and publishes listings across several marketplaces.
It even answers customer questions instantly. Our store looks more professional and sales have noticeably increased.

What took 48 hours now takes under 10 minutes, and clients regularly tell us how professional it feels.

We get thousands of comments and messages every week. BoldBellows built an AI system that replies instantly, filters spam and surfaces the important ones.
Engagement is up and our page looks active around the clock. It’s like having a full social media team that never stops.
